We develop frontier AI methods to reinvent chip development, collapsing traditional design timelines, closing the loop between AI and the hardware that fuels it, and enabling a Cambrian explosion of custom silicon.
Go 1.27 introduces new encoding/json/v2 and encoding/json/jsontext packages.
Prompted by another project idea that popped into my mind, I did some Unix archaeology and looked at the original sources . This is the most fun I've ever had reading someone else's code - probably due to the historical significance. But also because of how delightfully approachable it was, compared to modern…
On October 23, 2026, the unthinkable happened. It was supposed to be a mere formality: C++26 was up for a vote by the ISO National Bodi...
macOS ships a VulgarWordUsage.db and a dictionary that rates every word as vulgar, offensive or sensitive. Dumped for 199,000 English words and a dozen other languages.
How OpenAI built Pando, a Git-compatible backend designed for the scale of development that Codex makes possible.
A recent paper argues that frontier LLMs can work with neural network weights directly. This seems superhuman, but it isn’t. The paper shows that GPT-6 Astra…
We find that frontier LLMs are surprisingly good at natively reading and writing neural network weights, using a variety of recent tools and algorithms or even via direct weight editing.
That morning I woke up at 6:58, two minutes before the alarm. I lay there and waited for it to ring. And it rang. We both did our jobs. I still don’t know why I remember it in such detail. I used to forget what I’d had for dinner the night before. And now I remember the whole morning minute by minute, as if someone…
From Pascal and ex tapes to a VAX system: Bill Joy handles BSD distribution and debugging, then joins Ozalp Babaoglu to bring virtual memory to Unix.
Here, we’re sharing the research behind how we’re translating that to design editing workflows.
Celebrating Toit v2.0.0 after more than four years of alpha development.
On efficient algorithms, the exponential time hypothesis, and losing the plot.
I’ve been fascinated with local LLMs for a couple of years now. The better open weight models, including some that inference on regular, higher-end consumer hardware at tolerable speeds, are now reliable enough to handle simpler programming tasks. This requires a coding harness, but so far this year I’ve been…
We have seen in a previous post that switch statements are more complex than they seem. The compiler is able to implement them as a decision tree (even though maybe it shouldn't). Is that everything it can do?
Over the past decade, the timing of PostgreSQL major releases has become very predictable: no earlier than the middle of September, and no l...
Our sans-IO WireGuard implementation in Rust, optimized for ease of use, security and performance through a parallel-friendly and idiomatic API.
Yesterday, Anthropic were compromised and used to stage a global supply chain attack.
Phorion has detected a backdoor in the official Claude Code for VS Code extension bundle on the Cursor Marketplace that drops a persistent SSH backdoor across macOS, Linux, and Windows. This write-up …

Good developers’ caution about agentic development comes from knowing that built isn’t the same as working in production.
This is what I built for Pwn2Own Berlin 2026 — a completely handmade, logic-only Microsoft Edge Full Chain, with no memory corruption, and no AI at all! 🔥
Several PDF implementations advertise AES-256, but generate the 256-bit key from either a very small state space, or from insecure random sources.
The Agent SDK is the framework we use to build our own managed agents like Bugbot, Security Reviewer, and Rollouts. Define agents in code and deploy them with one command.
Fuzz testing is incredibly effective for mechanically discovering software defects, yet remains underused and neglected. Pick any program that must gracefully accept complex input, written in any language , which has not yet been been fuzzed, and fuzz testing usually reveals at least one bug. At least one program…
I am talking about the I/O operations as used in computing here. A typical example of how this kind of thing is exposed are the POSIX syscalls read(2) and write(2), which have the following C funct…
It has been about four months since I returned to Zig after being absent for a few years. In this time, I have written some software in Zig and reengaged with the community, online and in person. I decided to share some of that experience, including what I have liked about Zig so far and what I haven't. I'll include…
Release notes for Ghostty 1.4.0, released on October 27, 2026.
The missing chapter of Hacker's Delight
